"We want to give the joy we have in our lives to these little children," she says.

'It's not a bank'

This grand get-together is an "arisan" - a ladies club that combines saving with socialising.

It is a unique part of Indonesian culture, especially for those in the country's ultra-rich set.

Wulan and her friends are members of at least four of these ladies clubs.

"We collect money from all the members of the club on a monthly basis," she explains. "Then when it's your turn to draw the lottery, you win the pot. So it's like putting your money in a bank - but it's not a bank, it's a ladies club!"

But it's not just any old ladies club. Membership can come with a hefty price tag.

"The monthly amount you put into the pot can vary, from 1m rupiah to around 100m rupiah," says Wulan with a picture perfect smile. "Imagine the winnings then - each member walks away with $100,000 a month."

That's a fortune in this country where the minimum wage is around $250 a month.

Indonesia's new rich appear to be good for a lot of businesses, including legendary sports car maker Lamborghini.

It opened its doors in Indonesia in 2009 and since then the country has become its third largest market in the Asia-Pacific region.

"I think in a big city like this, maintaining the image of a good lifestyle is really important for young professionals," Johnson Yaptonaga, the owner of the Lamborghini showroom told the BBC.

"And owning an expensive car has become a trend for this group. Once you're in this community, you have to keep up with this lifestyle."

Surviving on $2 a day

But for many in Indonesia, life moves on a different track.

Rohma lives in a small slum near a railway track just a few kilometres from Dini Indra's branded bags studio.

Like most of Indonesia's poor, Rohma finds it hard to make ends meet

It is one of hundreds of slums peppered across Jakarta.

The cheapest handbag in Dini's studio could pay Rohma's rent for a year.

She lives in a tin shack with her husband and seven children.

She has seen the fancy cars and houses that have cropped up just a few hundred metres away from her slum - but they might as well be on a different planet. Her reality is filled with feeding seven mouths.

"My husband used to drive a taxi, and now he does odd jobs," she says as she cradles a one-month-old baby in her arms - her first grandchild from her eldest son.

"I cannot see a good future for us, because my husband doesn't work that often while we have to eat every day. For me as a woman it's been very tiring because I have a lot of kids, and my husband doesn't make a lot of money, and I feel really tired."

Life by the railway tracks is grim and Rohma's story is not unique.

Two-thirds of Indonesia's population lives on $2 a day - perilously close to the poverty line.

The ranks of Indonesia's mega-rich may be growing, but so too is the gap between the rich and poor.
